"Scientists at Harvard and Children's Hospital Boston announced Tuesday they have the green light to clone human embryos that could generate stem cell lines for specific diseases. The researchers join a small cadre of scientists worldwide attempting to do what a South Korean scientist claimed to have done, only to have his work unravel when it was exposed as a fraud. "We are convinced that work with embryonic stem cells holds enormous promise," Harvard's Steven Hyman said. Embryonic stem cells are the precursor cells to almost every tissue in the body; growing them could provide replacement tissues for diseases such as diabetes and cancer. In theory, the body would not reject the tissues from cloned embryos. Cloning requires inserting a cell from a patient into an egg and chemically triggering division of their union. So far, only a team at the U.K.'s University of Newcastle Upon Tyne apparently has created a cloned human embryo." By Dan Vergano. USA Today, Yahoo News Link to Article (last visited 6-7-06 NVS)
